OAKLAND, Calif. - The finale of the Mavericks' 11-day road trip had a little bit of everything.

It had J.J. Barea making just his second start of the season. It had Dennis Smith Jr. attacking the defending NBA champion Golden State Warriors for 22 points. It had Dirk Nowitzki's fourth double-double of the season.

It even had 7-2 Salah Mejri channeling his inner point guard on a fast break for a one-handed slam.

And, of course, it had another loss as the Mavericks got run down by a 28-8 Golden State run bridging the third and fourth quarters as they dropped a 121-103 decision to the Warriors.

What it didn't have was Devin Harris, who was traded earlier in the day and whose absence had a clear impact on the Mavericks' bench, which was badly outplayed by the Warriors' reserves.

Though the four games were spaced out, the toll of travel, a stressful week leading up to the trade deadline and the absence of Harrison Barnes who missed the final two games of the trip with a left ankle sprain doomed the Mavericks to a 1-3 record on the trip.

The loss Thursday dropped them to 17-38 and kept them tied with Atlanta for the worst record in the NBA.

The Mavericks actually were tied with the Warriors at halftime and had a 79-76 lead late in the third quarter befrore the 28-8 blitz ended any chance of them pulling off the upset.

Smith's game was strong offensively, although coach Rick Carlisle didn't like one particular aspect of it.

"I want to see more than three assists, to be honest," Carlisle said. "I know he can score. I just think he's got to keep working on the balance of his game. We got a lot of guys on our team that need help getting shots and I think he can help them."

With Barea starting, he dished out seven first-half assists and finished with eight.

Said Smith: "If he wants to see more than three, I got to get more than three. That's what I'm going to try to do next game - try to find my guys."

'He's at the top for me': Seeing Devin Harris get traded especially tough for his best friend, J.J. Barea

Asked if Barea was taking away his assists, Smith said: "J.J.'s fantastic. He comes out and finds guys every night, so I got to try to come out and emulate that."

The Mavericks also got a crazy highlight reel moment from Mejri, who blocked a Nick Young shot, scooped up the rebound and took it coast-to-coast, finishing with a fake to the wingman and a one-handed throw-down.

"That's what I do," Mejri joked afterward.

"He pulled the package out tonight," Carlisle said with a grin. "He had a nice post-up early. He went Dr. J on the break. The 27-footer, I'm not so sure about that one. But I'll have to check the shot clock. Maybe it was all right."

Actually, the official play-by-play had it as a 30-foot 3-pointer. Either way, it wasn't what you like to see out of your backup center.
